Solution found!, Has anyone with a Nuvi 680 updated the firmware from 3.7 to 3.8 and found

 

And found that it takes longer to acquire satellites? I thought it was just me, but a friend at work with the same unit just came out today and told me the exact same thing happened to him! How weird!

Has anyone else noticed this?

I am not sure if the other Nuvi 6XX models got the same update or not. It is the most recent update. Garmin tech support (the best) told me today he was unaware of the problem.

Maybe it is just me...

I was wondering the same thing

I have a 650 and it seems to take much longer to acquire sats than it had in the past. I just hadn't checked it closely before and after the update. Maybe I will try and back-out the upgrade and check it again.

How Long?

If you ask me, a nuvi 660 devotee, I say, emphatically, mind you: it takes too long. It should snap those satellites up like a crow on a june bug.

How long should it take for a nuvi6xx to acquire (enough) satellites? WAAS (isn't that the accuracy option?)? Day or night?

Enquiring minds....

Nuvi 680

After updating mine it seems to have no problem with the satelites although sometimes not always it will take longer then usual.........mine has frozen up twice now while traveling........it won't start working again till I shut it off and start it up again.........then it's ok.......plus I updated the bluetooth and now it won't load my phonebook plus it won't work like it did before..........Dave

Bluetooth

After updating mine at first I had the same problem but after rebooting my phone and re-pairing I had no more problems

Solution Found for Slow Sat Acquisition on Nuvi 680

I am not sure if it was the v2008 update or the 3.7 to 3.8 firmware update, but satellite lock was taking tooooo long. It was messing up everything.
I just bit the bullet tonight and did a hard reset. That's the turn on while holding the top right corner. Yeah, I lost my favorites, but I lock on to full satellites in 4 seconds. I still have all POIs intact.
I should have thought of this a week ago.

Hi fde1,

According to the support area an the Garmin website they say:

Question: I want to clear all the data in my unit, how do I do this?
Answer:
To clear all user data on the device please follow the steps below:

With the device off put press down and hold the 'Bottom Right' hand corner of the Touchscreen.
While pressing down on the screen, power the unit 'On' and continue pressing the screen until a message appears that says "do you really want to erase all user data."
Click 'Yes' and go through the set up again and this will clear all user data.
The unit will then go through the set up again and this will clear all user data.
Once the reset is complete please let the unit sit outside for about 15-30 minutes so that it can acquire satellites.

I don't know what effect, clearing all your user data, would have on satellite acquisition time, with your Nuvi 680. Can you tell me "why", clearing all your user data, makes your satellite acquisition time faster?

I have not figured that out yet.

Whether it was a corrupted favorites file from the install of v2008, or if it was the 3.8 firmware update made at the same time, I don't know. I do know that it happeded immediately after the upgrades and satellite acquisition became so slow. I even called Garmin to ask about it. As recently as yesterday, I used the gps to go to a location. Arriving there, I cancelled the go to action. Then, without turning anything off, told it to "go home". I gave me insane directions. Goofy. I cancelled it again and told it to go home a second time and it worked. It has been doing this for a week or so. Usually when I need it the most.
The reset last night made an awesome difference in speed and reseption. AWESOME. I now get 6 sats inside my home in less than 8 seconds. Works for me! Try it.

Hi fde1,

I'm stunned...

I went through the "reset" you described, in an earlier post. A few minuter ago I turned on my Nuvi 670 and went to "view map" display. Then, after lifting up the built-in antenna, I placed the unit in the window frame at home and it acquired the satellites, in under 5 seconds. Prior to that my acquire times were pretty slow, sometimes I'd be a mile or more down the road before the satellites and my Nuvi 670 connected.

I'll keep observing the acquire times through subsequent use and i'll let you know if those acquire times are consistent or at least faster than they were before the "reset"...

Regards,

Tailspin

Nuvi 680

When my Nuvi 680 did not acquire a signal anymore I took it back to Best Buy and they gave me a new one.............Dave

It is the bottom right, sorry bout that

I wonder what the top right will do?
Thanks for the clarification tailspin.

I just reset my 680 and it too seems to work faster. Thanks for the info.

Wow! Huge improvement!

Thank you Frank and Tailspin. It worked perfectly on my 650.

Before reset - 42 secs to acquire sats

After reset - 4 secs to acquire sats

Backup and restore favorites?

Since doing this "reset" will delete your favorites, is there a way to backup and restore them?

I have to agree with tailspin's original post and inquiry. I don't see how a clearing user information will affect acquisition time.

I found it typical with my nuvi 660 to take around 40 seconds to acquire satellite signal on a COLD boot, and even longer while in a moving vehicle. After the unit has warmed up, it takes less than 5 seconds to acquire signal.

Per nuvi 610/660/670 Owner's Manual, page 65, under GPS Performance:
====================
Acquisition times*:
Warm: <1 sec
Cold: <38 sec
Factory reset: <45 sec

*On average for a stationary receiver with a clear view of the sky
====================

Could it be that these perceived faster acquisition times after a reset is due to the devices being already warmed up?

If you have MapSource, you can download the Favorites from your nuvi into MapSource. Otherwise, with your unit hooked up to your computer, locate the current.gpx file on your garmin drive and copy that to your computer. Then you can copy it back to your nuvi if you need to.

Just reading the gpspassion

Just reading the gpspassion forum, users seem to be having all sorts of problems with the new upgrade. Several are reverting back to the ver.3.80, or another version.

Taking longer to acquire satellites

After reading the thread here, I did a reset and it worked great. I was getting sat data in a few seconds. I then downloaded the new MSN data download update last week and noticed the same problem again it was taking several minutes to acquire satellites. I then reset the unit and it was back down to few seconds for sat acqusition.
Now here is the real strange thing. The first time I reset the unit (last week) I lost all my favorites and had to reprogram "Home"; when I did it again a couple of days ago, the Nuvi 680 still had the favorites and "Home"
Strange huh!!!
Anyone else run into this after the MSN download?

resetting?

I know resetting your nuvi sounds like a great solution but it shouldn't be all the time. I think it has to do with how much data is stored on your unit. once i started to load mp3s, pois... my unit takes longer to boot up and also find satellites. I may be wrong of course.

Latest Version?

Is there a version newer than v3.80?

latest firmware

updated fine but still no traffic support for Canada at least not in Toronto

Odd

Oddly enough, after doing this reset the 680 has defaulted to Kansas City, thinking that it is physically located in Kansas City. It is acquiring sats. now and will determine it's physical location shortly I suppose?

Loss of personal stuff more of a side effect, not the fix?

avd24 wrote:

Perhaps it isn't the clearing of the personal data that does it but other things that get reset or cleared (which is why it has to reacquire sats again for the first time and set up.

The loss of personal stuff is probably just a side effect of the reset (a red herring), not the actual reason for the better performance.

I wonder if this will work on my nüvi 200 which has been very slow to acquire satellites. I did perform one firmware update after I received it for Xmas.

What is the average rate of acquisition time?

I was just wondering how long acquisition time should take on average. At my home, acquisition seems to take a good deal of time (up to a minute or two - or so it seems - definitely not 5 or 4 seconds). I will add that this is after a cold boot of the device. I'm not sure which version of the firmware I have (I may have upgraded it as soon as I had the chance, I can't remember), but it always seems to take this long. I always thought it was due to the location of my home, since at other times it seems to acquire quite rapidly. There are several tall trees around my home, but nothing overwhelming (I live in the city). Now I am not sure what to think.
